The invention relates to the technical field of the combination of environment monitoring and wireless control, in particular to a system capable of simultaneously monitoring a plurality of pathogenic microorganism aerosol pollution colonies. The system is characterized by comprising a control terminal and at least one microorganism sampler, and data transmission between a wireless module inside the control terminal and a radio frequency module of the microorganism sampler is performed in a wireless transmission mode. In the invention, a wireless networking technology is utilized to realize multipoint sampling with multiple samplers at the same time, one control terminal in a certain distance is used for unified control, and the problem of real-time, intelligent and multi-place acquisition is solved. The invention has the advantages that the system is easy to carry, small in size, wider in control range and farther in control distance, the control is more real-time, gas circuit connections are fewer, the suction of sampled gas is more stable, the separation of gas in water is more complete, a monitoring result is accurate and reliable, and better personal safety can be ensured by utilizing the system to monitor personnel.

The invention discloses a three-phrase high-power remote control socket which comprises a PVC box, an alternating current contactor, a switch power source module, a remote control receiving and controller assembly, a power source output socket, an input power line, a receiving antenna, an indicator light and a remote control transmitter assembly. The three-phrase high-power remote control socket is a power source switch device capable of remotely controlling water pumping and applying of a three-phase alternating current motor over 1 kilometer away from the device and factory dangerous place production machining and the like easily, conveniently and safely. When a three-phase motor driven by a rural tractor or a diesel conducts liquid dung pumping and applying work, due to the fact that an infusion pipeline is long, it is avoided that people need to walk back and forth to switch on the power source and switch off the power source, and the purpose of saving the labor or lowering the labor intensity is achieved. The three-phrase high-power remote control socket has wide application significance in the industries of industry, agriculture, forestry, fishery, landscapes and the like and is wide in work range, small and exquisite, convenient to operate, high in practicability and as simple as a power source plugboard in combined assembly.
